To all whom/it may concern:

Be it known that I, WILLIAM L. TETER, of the city and county of Philadelphia, and State of Pennsylvania, have invented'an Improve ment inv Machine-Belts, of which the following is a specification.

My invention has reference to woven ma- I chine-belts; and it consists, essentially, of one or more layers of metal warp interposed be tween two ormore layers of cotton warp, each layer beingformed of two scis ol' warps and a suitable filling, and these layers of warps being bound together byv suitable binding-warps,

h which extend entirely through :the various layers and securely bind them together, and in details of construction, all of which are fully set, forth, in the. followiligaspecificalion- The object of this inventionis to form a ma-chine-belt which shall be non-extensible in the direction of its length, and in which none Y of the layers of metallic warp should come in contact with the band-wheels, being thoroughly protected by layers ot' cotton warp, thereby producing not only a more perfect x belt, but one which shall have a greatly-in- 1 creased durability.

In the drawings, Figure l is a longitwflina sectional elevation on line ma showing the various layers composing the belt and how they are bound together; and Fig. 2 is a crosssect-ion oi. same on line 3/ y.

'1! represents layers of cot-ton warp, and B represents layers of combined cotton and metal warp, in which E are the metal warps.

.4 5 Asis sceuinl ig. 1, the layers cmbodyingthe metal warp are separated'by the layers composed wholly oE-cotton warp, thereby being prot ected from each other, and as the outer layers-are of cotton the metal warp is'protectjed fronibeingcutf'or worn by running over the pulleys or by coming in contact with eigternal' object's. 1 1

tice a single filling-thread is used, as indicated in dotted lines, passing between the warps of j alternate layers, thus binding them thoroughly together at their edges, it is evident that each layer may have its own specific fillingthread.

The" light dotted lines connecting the. filling-lhreads indicate their passage at one edg of the belt, while-the heavy. dotted lines indicate their passage at the other edge of the belt, showing that a strong iirmsel' vage is insured. These layers II and B are firmly bound together by the binding-warps F, which pass around the filling-threads of the two outer layers of the belt, thus binding every layer throughout -theirentire-surface tightly together, making the belt extremely compact-and entirely protecting the metallic portions thereof, and the peculiar construction prevents any possibility of the metallic warp 1 working out while the belt is in use.

Any number of layers may be employed;

but in all cases the outer layers are of cotton D are the filling threads, and while in, pracor fibrous material alone, while the alternate inner layers may be either metal alone or preferably metal and cotton combined; hence combination with iilling and'binding threads to unite the several layers of warp to form a compact belt, substantially as and for the pur pose specified.

2. In a woven machine-belt, three or more cotton layers of warps, every alternate layer being furnished with a series of metal warps, and in which the two outer layers are of cotton only, in combination with filling and binding threads to unite the several layersof warp to form a compact belt, substantially as and for the purpose specified.

- 3. A machine'belt composed of one or more layers of combined metallic and col-ton warp and three or morelayers of cotton warp, the metallic warp being inclosed between the cotton layers of warp, and-in which the wearingsnrface, or that which runs next to the pulleys,

is made with a double layer of cotton warp, substantially as and for thepurpose specified.

4. A maehinebelt composed of one or more layers of combined metallic and cotton warp and three or more layers of cotton warp, the metallic. warp'being inclosed. between the cot ton layers of warp, and in which the wearingsurface, or that which runs next to the pulleys, is made with a double layer of cotton warp, in combination with a single filling-thread, which passes successively between the. warp of each layer, substantially as and for the purpose specified.

A machine-beltconsisting of the combination of the cotton warp H, the cotton and metallic warp B, interposed between them, suitable filling-threads, and binding-warp, substantially as and for thepurpose specified.

6. In a woven machine-belt, one or more layers of metallic warp interposed between two or more layers of cotton warp, in combination'with suitable filling-threads and binding-warp, the lattenpnssing entirely across all the layers of warp, binding them together, substantially as and for the purpose specified.
